Debian Security Advisory DSA-090-1                   security@debian.org

Package        : xtel
Problem type   : symlink attack
Debian-specific: no

The xtel (a X emulator for minitel) package as distributed with Debian
GNU/Linux 2.2 has two possible symlink attacks:

* xteld creates a temporary file /tmp/.xtel-<user> without checking
  for symlinks. 
* when printing a hardcope xtel would create a temporary file without
  protecting itself against symlink attacks.

Both problems have been fixed in version 3.2.1-4.potato.1 .

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.


Debian GNU/Linux 2.2 alias potato
- ---------------------------------

  Potato was released for alpha, arm, i386, m68k, powerpc and sparc.
